Abortion refers to the termination of pregnancy before the fetus is viable outside the womb, typically defined as before 20 to 28 weeks of gestation depending on regional guidelines. Understanding the context requires distinguishing between spontaneous loss and induced termination, with the latter further split into safe, legal procedures and unsafe, clandestine procedures. In Nigeria and many resource-constrained settings, unsafe abortion remains a major public health challenge, contributing significantly to maternal morbidity and mortality. Unsafe procedures are frequently performed by untrained providers using crude instruments or dangerous methods, which drastically increases the risk of severe physical complications.
Hemorrhage is the most common acute complication following an incomplete or unsafe abortion. Retained products of conception prevent the myometrium from contracting effectively, leading to continuous, heavy bleeding. If blood loss is rapid and unmanaged, the patient quickly progresses to hypovolemic shock.
Introduction of bacteria into the sterile uterine cavity during an unsafe procedure frequently leads to ascending infections. Endometritis is the initial localized infection, which can rapidly spread to the myometrium, parametrium, and pelvic peritoneum.
Blind instrumentation during unsafe terminations carries a high risk of mechanical trauma. The uterine wall, especially if softened by pregnancy or infected, can be easily punctured by sounds, dilators, or curettes. Beyond the uterus, surrounding intra-abdominal structures such as the bowel, bladder, and major blood vessels may also sustain lacerations. A perforated uterus requires immediate surgical evaluation, as conservative management is only appropriate in very specific, stable cases. Nurses must monitor closely for signs of peritonitis, such as severe abdominal rigidity and rebound tenderness, which indicate leakage of bowel contents or pelvic blood into the peritoneal cavity.
Complications can manifest weeks, months, or even years after an abortion procedure. Asherman's syndrome, or intrauterine adhesions, develops from aggressive curettage that damages the basal layer of the endometrium, resulting in amenorrhea or recurrent pregnancy loss. Psychological sequelae are also common, ranging from transient grief to severe post-traumatic stress disorder, particularly when patients face social stigma or lack support systems. Furthermore, repeated uterine instrumentation or untreated cervical trauma can lead to cervical incompetence, increasing the risk of spontaneous mid-trimester losses in future pregnancies.
A comprehensive nursing assessment for a patient presenting with post-abortion complications requires a systematic approach. The nurse begins with a thorough history, noting the estimated gestational age, the method of abortion, and the time elapsed since the procedure. Vital signs are checked immediately to detect early indicators of hemorrhage or sepsis. Abdominal palpation helps assess tenderness, guarding, or distension, while a sterile speculum examination evaluates the source and amount of vaginal bleeding, cervical dilation, and any visible tissue in the os. Laboratory investigations, including a full blood count, blood grouping and crossmatching, and clotting profiles, are coordinated promptly to guide medical interventions.
Management of abortion complications centers on stabilizing the patient, evacuating retained products of conception, and treating infections. Intravenous access must be secured immediately with large-bore cannulas for fluid resuscitation and blood transfusion if hemorrhage is present. Broad-spectrum antibiotics are initiated promptly when infection is suspected. Evacuation of the uterus using manual vacuum aspiration or sharp curettage is performed once the patient is stabilized. Beyond physical care, comprehensive post-abortion care includes compassionate counseling, treatment of emotional trauma, and provision of effective family planning methods to prevent unintended repeat pregnancies.
